The Sun Hydraulics DMDATNN724 (DMDATNN724) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is notable for its robust construction, including a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar). It features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications where capacity is less critical. The DMDATNN724 requires no minimum hydraulic pressure to operate, making it highly versatile in various hydraulic systems. It includes options for manual override with a detent mechanism designed for temporary actuation; this feature has a mechanical life expectancy of approximately 7,000 cycles. The valve is fitted with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. This model also benefits from a wet armature design where the working fluid surrounds the armature. While this design aids in cooling, it can lead to fluid degradation if the coil remains energized over extended periods. The valve's interchangeability with other Sun Series 1 solenoid products adds to its flexibility in installation and maintenance. Additional technical specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 3000 psi rated at about 5 in\u00b3/min (80 cc/min). The switching frequency can reach up to 15,000 cycles per hour. For installation and maintenance ease, it incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. This model's compact and efficient design makes it an ideal choice for sophisticated hydraulic systems requiring reliable directional control.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
